OK, that's a good point -- but I'm sure you'll acknowledge that taking "fast" out of the equation changes things significantly (in terms of being able to do a technique properly and effectively without hurting the noob).

Absolutley, fast is for higher level practice, when you know how to protect yourself, not for noobs.
